s oiams. f 101.2854182) "'Th'is invention relates to'pipe connections and has for :an objectfto provide an improved con- I'structionwhereby pipes Vmay be joinedy rmly and ,accuratelyin an' minimum time and with mini- Another object of theinventionis to provide a construction which 'may be used in connecting pipes which act as conduits for electric wires, the

structure being such that a strong, mechanical l structure is presented and one capable ofr being quickly applied. v

A further object of the invention is to provide an improved connection for pipes for any desired e, purpose, the structure being such thatl the center l5 -part is reinforced and the other parts -formed to present a gripping and holding action for lholding the ends of the pipes juxtaposed. e In the accompanying drawingf FigureV 1 is a top plan view of theradjacent ends f of two pipes and a coupling embodying the invention applied thereto, part of the coupling being broken away to illustratel the construction thereof; Y f

Figure 2 is a View similar to Figure 1 but show ing the parts in their locked position;

Figure 3 is a sectional View through Figure 2, on the line 3 3; e

Figure 4 is a-transverse, sectional view through ,A Figure 3 on the line 4 4.

Referring to the accompanying drawing by numerals, v1 and 2 indicate pipes with their respective ends 3 and 4 juxtaposed, as clearly shown in Figure 3. The connector 5 is adapted tobe quickly applied and to rmly hold the pipes in their aligned position. This arrangement isparticularly adapted for conduits carrying electric wires, but may be used for connecting pipes for many other purposes. The connector 5 is formed from A a tubular body 6 having an inwardly extending annular iange 7 against which the ends 3 and 4 rest. The tubular body 6 is adapted to fit the pipes 1 and 2 with a free sliding nt, and in order to lock the pipes in their end-to-end position locking wedges 8 and 9 are provided. These wedges are tted into the respective raised portions 10 and 10'. Y

As both of these raised portions and as both the wedges are identical in structure, a description of one will apply to both. As shown in Figures 1 to 3, the raised portion 10 is formed with a rectangular socket 11 merging into a neck opening 12, which in turn merges into laterally extending pockets 13 and 14. Between the pockets 13 and 14 there is arranged a V-shaped structure 15 which acts as a cam for kdelecting the lockingV k'then used to drive out the Wedge 8.

ngers 16 and 1'7, which ngershave locking knobs 18`and 19 positioned to engage the cam'l and be diverted into the pockets 13v and 14 when the fingers 16 and 17 havebeen bent'as-'shown in Figure 2. lNormally the knobs 18 rand 19lare 60 a distance apart vw'nichpermitsthem to be easily moved through'the neck opening.y 12. `After'ha'ir- 'ing moved throughk the neck opening 12,the'end 20 is struck with a hammer or other implement and the wedge driven into the position shown in Figures 2 and 3. It will be understood that the other'vvedge is operated in a similar manner, so that the complete connector is in operative posi-` tion when the parts are as shown in Figure 3.

It will be understood that the knobs 18 and 19 70 are round and interlock with the shoulders 22 and 23, but may be forced therefrom by an implement placed in the depression24 and driven towards the right, as shown in Figure 2. This will cause the fingers 16 and 17.to bend back to-75 'A substantially the position shown in Figure 1. The portion 10 is provided with a notch orY cutaway part 21 so that a chisel or other implement may be iitted into the depression 24 and y When it is desired'to connect the ends of two pipes together, the tubular body 6of the'connector is slipped over the end of one pipe until the ange 7 strikes the pipe. The other pipe is then slipped into the position shown in Figure ,3 and then the wedges 8 and 9 are driven 'into vformed with a "socket near each end positioned .out of alignment, each of said sockets having locking pockets extending therefrom and a wedge for each socket, said body between said pockets being inclined in opposite directions and merging into the respective pockets, each of said wedges having projecting members adapted to engage the inclined portion of said body and be spread '100 thereby so as to enter said pockets While the wedge is being forced into its functioning position, whereby the wedges are locked against accidental removal. Y

2. A connector'for'connecting pipes, compris- 105 ing av tubular body having a socket at each end and inclined pockets extending from each socket,

a wedge for each socket adapted to be forced into position for pinching the pipes extending into the tubular body for locking the pipes in place,l'10

each of said Wedges having a pair of. normally parallel ngers adapted to be spread and thereby forced into said pockets when the wedges are forced into functioning position, whereby the wedges are normally prevented from reverse movement.

3. A pipe connector comprising a tubular body having on diametrically opposite sides and also on opposite ends raised portions having therebeneath a wedge receiving socket, said sockets having a neck portion extending therefrom merging into laterally extending pockets, the material of said body between said pockets being substantially V-shaped to present cams, a wedge for each of said sockets, each of said Wedges having a pair of ngers extending therefrom and merging into rounded ends, said fingers being spaced apart suiiiciently to pass through saidV neck and engage said cams and be bent by the cams so that the ends will be positioned in said pockets when the wedge is in full functioning position. n Y

4. A pipeconnector including a tubular body having an inwardly extending annular flange against which the ends of two pipes are adapted to abut, and a pair of wedges, Vsaid wedges being arranged at opposite ends of the tubular body and acting against the` tubular body and the respective pipes for locking' the pipes' in. the tubular body, each of said Wedges having means interlocking with the tubular body for preventing accidental removal.

5. A pipe connector including a tubular member for receiving the ends of two pipes, a socket in the end of said tubular member, said socket merging into a pair of laterally extending pockets, and a wedge arranged in said socket, said wedge having a pair of extending arms positioned in said pockets when the wedge is in functioning position.

6. A pipe connector comprising a tubular member for receiving the ends of pipes to be connectedy said tubular member being formed withk an inwardly extending member for centering the adjacent ends of said pipes, said tubular member having a socket at each end, said socket being at opposite sides of said tubular member, a Wedge fitted into each socket for pinching the respective pipes for locking the same in the tubular member, and means Vforming part of the tubular member and part ofthe respective wedges arranged beyond the socket, said meansv interlocking and normally holding' the Wedges in their functioning. position. y
